Updated stats for Marv's mod as of 9/2/2015. I unfortunately don't have a change log but at first glance there appears to be changes to some sprint-out times, reload times and slight adjustments on the ROF for some weapons.
Also people should play this. It's fun. Apparently the server on the first page is still up.
